I'm a 25 year old female and never been in a relationship let alone gone on a date, how bad is that?

Growing up of course I've had crushes on guys and I have been asked by guys. It's just the guys I was asked out by I never really was attracted to physically, mentally or emotionally. I feel I've been so busy with life as far as school, work and helping my family and friends that I have missed out on a big part of growing up. I have no clue how to flirt with guys, at least I don't think so because they all treat me like a friend, I don't know how to find guys who would actually like someone who hasn't been in any sort of relationship.

Guys, would this freak you out about a girl you were getting to know? Should I even tell a guy if I meet one?

No I'm actually really comfortable with myself and I'm happy with who I am beside this part of me. I'm starting to become self conscious of it more over the years. I have no legit reason why it didn't happen.
